hw/scripts: Add adapter selection for pyocd
Added support for selecting a specific debug probe using USB serial
number via environment variables.
This is useful when multiple boards are connected and pyocd cannot
choose which one is target.
Supported variables:
- CMSIS_DAP_SN for CMSIS-DAP
- STLINK_SN for ST-Link
- JLINK_SN for J-Link
Example:
STLINK_SN=0666FF495157808667171335 newt load nucleo-f767zi-blinky
